To dit' who/m it may concern.'

.lle it lino-wn that l, Jona Klemme, Jr., a citizen of the UnitedStates, residing at North rlrdains, in the county of Berkshire and Stateof lrlassachusetts, have invented new and useful lmprovements in Take-UpScales, of which the following is a specification.

'.lhe purpose of this invention is to provide a gage for use in thetextile industry to determine the percentage of taleup in the warpthreads of fabric thereby avoiding the slow and tedious process ofobtaining said percentage as by measurements and subsequentcalculations.

'llhe percentage of take-up in weaving is for the purpose of determiningthe amount of warp threads or yarn required to weave a fabric of anylength. According to the method usually employed, the fabric to beanalyzed is cut in a manner to enable one or more of the warp threadstol be obtained after which said threads or yarn are measw ured bothprior to and after being stretched. After the measurements have beendetermined, the length of the piece of cloth is subtracted from thelength of the warp thread when straightened out and the difference isdivided by the length of the warp thread or yarn when straightened andthe quotient is multiplied by one hundred which gives the percentage oftake-up in weaving.

ln accordance with this invention a gage or rule is provided having aportion of a given length laid off corresponding to the length of thefabric whose percentage of take up is to be determined, said gage orrule also having a percentage gage beyond the said laid off portion toindicate the percentage of take-up of the fabric, the gradua tions ofsaid percentage scale proportionately increasing in length in successiveorder from the initial marking, said graduations being numbered tocorrespond with the required percentages.

The invention further contemplates a gage or rule having two lineargraduated scales, both scales having a point in common from whichreckoning is made, one scale indicating linear measurements according toany recognized system and the other scale indicating the percentage oftake-up in the warp threads of the fabric of a given length determinedby the linear scale and having its graduations proportionatelyincreasing in length in successive order from the given point in thelength of the linear scale.

The drawing illustrates a gage provided with a linear and a percentagetake-up scale embodying the essential features of the invention.

llhe gage or rule comprises a body l of any length, width or thicknessprovided along one edge with a scale 2 for indicating linearmeasurements, and having a second scale adj acent to and paralleling thelinear scale to in* dicate the percentage of taleup in the warp threadsor yarn of a fabric ofgiven length. rllhe linear and percentage scalesmay vary according to the construction of the gage vor rule, but saidscale graduations have a determinate relationship. YThe linear' scale islaid olf in inches and fractional parts thereof. The percentage scale 3has its graduations determined with reference to the linear scale or toa part thereof. The numeral l indicates the point in common to bothscales 2 and 3 from which the measurements are made. The numeral 5indicates the point in the length of the linear scale from which thegraduations of the percent age scale are determined and ascertained. Thedistance between the numerals si. and 5 corresponds with the length ofthe fabric whose percentage of take-up is to be determined. Thegraduations of the percentage scale are determined by measurements andcalculations with reference to the distance between the numerals l and5, or the laid off portion of the gage or linear scale as a unit ofmeasure. It is to be understood that the graduations of the percentagescale may be indicated in any way and for convenience they aredesignated by multiples of 2. It has been found that the graduations ofthe percentage scale increase proportionately in successive order fromthe initial point 5 as indicated most clearly in the drawing and this isthe case in every instance no matter how the graduations of thepercentage scale may be indicated.

To use the gage the cloth or fabric whose take-up is to be determined isout to a length corresponding to the laid olf distance between thepoints 4 and 5 of the gage which in the present instance corresponds tosix inches. After the cloth or fabric has been cut to the predeterminedlength one or more warp threads or yarn are obtained and the same arestraightened, one end being placed at the point 4 andthe opposite endreaching to and beyond the point 5, the distance of reach beyond thepoint 5 determining the percentage of take-up on reference to thepercentage scale 3; Should the end of the thread or yarn extend to thegraduation indicated by the numeral 2 on the percentage scale, it may beknown that the percentage of take-up is 2. On the other hand, should theend of the thread or yarn extend to the numeral 4, or to the numeral 6,it may be known that the take-up is either' four per cent. or siX percent. as the case may be.

The percentage scale 3 is determined by reference to the length betweenthe points 4 and 5 of the linear scale which is six inches, but thedistance between the points 4 and 5 may-be of any length and thepercentage scale determined with reference thereto and when onceascertained the gage remains fixed and it is necessary to cut the fabricor cloth to the length designated by the distance between the points 4and 5 in order to ascertain the percentage of take-up thereof.

Having thus described the invention, what is claimed is- A Weavers gagefor ascertaining the percentage of take-up in the Warp threads of afabric, the same consisting of a body having a linear scale regularlygraduated in standard units of measure and having a percentage scaleparalleling a portion of the linear scale, said percentage scalebeginning at a distance from the zero point of the linear scale equal tothe predetermined length 0f the warp threads unstretched, and thenumerals designating each percentage graduation being determined bydividing the difference between such given length of a warp thread andits length after stretching by the last named length, and multiplyingthe quotient by one hundred, and each such graduation of the percentagescale being at a distance from the zero point of the linear scale equalto the length of the cor responding thread when stretched.

In testimony whereof I ailix my signature in presence of two witnesses.
